| 摘 要： | 本研究工作是在利用航空遥感信息进行黄土丘陵沟壑区侵蚀环境系列制图的基础上,对黄土侵蚀环境动态变化作了初步分析探讨。通过利用山西省离石县王家沟流域不同时期的航空像片,应用先进的地理信息系统软件ARc/INFO系统编制出了该流域不同时期,不同时段和不同类型的侵蚀环境系列图,包括影响侵蚀因素系列图、土壤侵蚀量分布图,流域沟谷形态变化图,时段侵蚀平均发展速度图以及治理评价图,并在此基础上,利用环境动态分析法分时段分析了流域侵蚀状况变化及其环境的变化。在侵蚀环境的分析中·不仅分析了影响侵蚀的自然因素,还揭示了人为因素对侵蚀的影响。研究结果,为黄土高原小流域水土流失综合治理措施的制定提供了科学依据。

| Abstract: | On the basis of application of aerial remote sensing information to erosion environmental systematic mapping of valley and gully area on loess plateau, an extensive study on loess erosion environment changes has been made in this paper. By using the different period aerial-photos of Wang Jia Gou, a small basin, which located in Li Shi county, Shanxi province, and by using the advanced geographical information system software ARc/INFO system, we have compiled the erosion environmental systematic maps of different periods and of different types: multiple factors erosion map, erosion amount distribution map, basin's valley and gully shape change map, average erosion developing speed map and basin multiple management evaluation map. On the basis of above works, we have made an analysis of erosion situation and environment changes in this small basin in different period by using environmental dynamic analysis method. Many-impacts, especially, the human impacts has been emphasized in the erosion environmental analysis.The results of this work has provided a scientific basis for multiple management for small basin on Loess plateau. |
